This is v4 of adding RK356x VOP2 support. Due to popular demand I added
a changelog to each patch, at least starting with changes to v3, I
didn't care to add the older changes as well. I hopefully integrated all
feedback I received to v3. Additionally I added some patches to the HDMI
driver to support resolutions up to 4k@60Hz. The patches are mostly
taken from the downstream kernel. Some have been send to public lists,
but were never applied upstream for reasons I do not know. The patches
are a bit more intrusive than needed for my case, but are present in the
downstream kernel for a long time, so I decided just to take them
instead of stripping them down to my needs. With these patches I
successfully used the driver with 4k@30Hz. 4k@60Hz doesn't work for me,
I hope this is due to my low quality cable.

Changes since v3:
- added changelog to each patch
- Add 4k support to hdmi driver
- rebase on v5.17-rc1
Changes since v2:
- Add pin names to HDMI supply pin description
- Add hclk support to HDMI driver
- Dual license rockchip-vop2 binding, update binding
- Add HDMI connector to board dts files
- drop unnecessary gamma_lut registers from vop2
- Update dclk_vop[012] clock handling, no longer hacks needed
- Complete regmap conversion
Changes since v1:
- drop all unnecessary waiting for frames within atomic modeset and plane update
- Cluster subwin support removed
- gamma support removed
- unnecessary irq_lock removed
- interrupt handling simplified
- simplified zpos handling
- drop is_alpha_support(), use fb->format->has_alpha instead
- use devm_regulator_get() rather than devm_regulator_get_optional() for hdmi
regulators
- Use fixed number of planes per video port
- Drop homegrown regmap code from vop2 driver (not complete yet)
- Add separate include file for vop2 driver to not pollute the vop include
